Product Description
Styrene butadiene rubber (SBR), also known as polystyrene butadiene copolymer. Its physical mechanism performance, processing performance and service performance are close to those of natural rubber, and some properties such as wear resistance, heat resistance, aging resistance and vulcanization speed are better than those of natural rubber. It can be used with natural rubber and various synthetic rubbers, and is widely used in the production of tires, tapes, hoses, wires and cables and various rubber products. It is the largest universal synthetic rubber variety and one of the earliest rubber varieties to realize industrial production.
